An example of sqlite_column_* functions is in sqlite_blob.exw. Maybe rename that
file to sqlite_prepare.exw to make it clearer.

Here is the explanation of what sqlite_column_* functions do:
When you use sqlite_prepare()/sqlite_step() functions to READ from database, you
should then use sqlite_column_* functions to retrieve the data of found rows.
sqlite_column_* functions are used only when reading from database, whereas
sqlite_bind_* functions are used both when writing and reading the database.


Maybe add this info to the documentation of sqlite_step() because it's
important:

-- Returns SQLITE_DONE, SQLITE_ROW, SQLITE_BUSY, SQLITE_ERROR or SQLITE_MISUSE,
-- see http://sqlite.org/capi3ref.html#sqlite3_step
-- When reading from database, SQLITE_ROW is returned if there were any row(s)
found
-- and are ready to be read with sqlite_column_* functions.
-- SQLITE_DONE is returned if there was no row found.
